SPINNING-TOP.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Applic tion fil d August 23, 1904. Serial N0x 221,889.

To all whom it may concern.-

Be it known that I, EMIL FRIZ, manufacturer, a subject of the Germ anEmperor, and a resident of Goppingen, in the Empire of Germany, (whosepost-office address is the same,) have invented certain new and usefulImprovements in Spinning-Tops, of which the following is an exact, full,and clear description.

This invention relates to mechanism for spinning tops by means of aseparate appliance comprising a spindle which is set in rotation by avertical movement, and has for its object to rapidly spin one or moretops by means of such appliance. In order to spin the top, the spindleof the appliance is simply depressed thereon, and the top is kept inconstant motion for a suitable length of time by repeating theabove-mentioned manipulation.

The invention is carried out by the arrangement of a suitably-shapedsurface on the top and a suit-able coupling-head on the spindle, whichengage with one another frictionally or otherwise as soon as the spindleis pressed onto the top when on the ground in order to start the top andtransmit to it the rotary motion of the spindle, so that the spinningmotion can be produced easily and rapidly only by pressing the spindleonto the top.

The surface and coupling-head of the improved mechanism may be formed ofany suitable material.

Reverting to the accompanying drawings, Figure 1 represents theactuating-spindle before being placed on the top; and Fig. 2 representsthe actuating-spindle after it is set in rotation by pressing it on thetop, which rotation is simultaneously imparted to the top.

The spindle is illustrated at that moment in which it is to be rapidlyremoved from the top, so as to allow the latter to spin freely. Fig. 3is a plan of the top.

0 is a handle, and E is ahollow spindle which is slidably arrangedwithin the handle C. A helix B is fixed on the handle 0 and extendsthrough a hole f in the top of the said hollow spindle E. If the hollowspindle E is slid into the handle C against the action of a spring F,located in the handle 0, by engagement with the helix, a rotation of thehollow spindle is produced. Thus by exerting a thrust or pressure on thetop by means of the hollow spindle the top is rotated and set into thebalancing position.

Owing to the peculiar arrangement of the coupling members, the impulsecan be given to the top even when it rotates. The arrangement of thecoupling members is such that all guiding means are dispensed with andis characterized by the fact that one coupling member forms at the endof the hollow spindle a frictional part or a head provided with lugs,and the other coupling member is formed by a recessed or conical-shapedsurface on the top.

It is immaterial how the coupling members are shaped, provided that theyare adapted to engage with each other frictionally or otherwise.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim, and wish to secure by Letters Patent, is

In combination with a top having a frictional part, a hollow spindlehaving a corresponding part adapted to engage with said frictional part,a hollow handle within which the spindle is slidably arranged, a helixrigidly secured in the handle and engaging with the spindle to rotatethe same when the handle is depressed and a spring in the handle forreturning the parts to normal position, substantially as described.

This specification signed and witnessed this 22d day of July, A. D.1904.
